Abstract: An open grid fabric for reinforcing wall systems and a method of making same. First and second sets of substantially parallel, selected rovings are combined using certain knits, leno weaves, or adhesive methods.      The rovings are direct-sized with at least a silane sizing and preferably have a linear density between 100 and 2000 grams per thousand meters and are arranged at an average of 3 to 10 ends per inch. A polymeric coating is applied to the fabric at a level of 10 to 150 parts dry weight of resin to 100 parts by weight of the fabric while assuring that the open grid remains open. A method for reinforcing a wall system and a wall segment product utilizing the novel open grid fabric of the present invention are also disclosed.

Abstract: A scraper device for attachment to a broom of the type having a head and a handle, the handle having a lower end for mounting to the head. The scraper device is comprised of a blade carrying member, having an upper end and a lower end, for attaching to the broom in a position such that the upper end of the blade carrying member abuts against the handle and the blade carrying member extends downwards and forwards over the head. As well, the scraper device includes means for attaching the blade carrying member to the broom when the blade carrying member is positioned for attachment to the broom so that the blade carrying member is secured to the broom and movement of the scraper device relative to the handle is restricted. Further, a scraper blade is located along the lower end of the blade carrying member so that debris may be scraped from a surface by the scraper device when the orientation of the broom is reversed from that normally used for sweeping. Finally, the scraper device may include first means, associated with the blade carrying member, for bracing the handle and supporting the blade carrying member when the blade carrying member is attached to the broom.
Patent CA-2134541-C (CA)

Granted: 1999-02-09
Abstract: A passive  infrared detection  and conversion  circuit includes a pyrosensor, a current amplifier, a capacitor, and a signal processor circuit.  The signal processor is operable to charge the capacitor to a first voltage level and to measure a capacitor discharge time, the time required for the capacitor to discharge from the first voltage level to a second voltage level.  The signal processor is further operable to generate an electrical control signal responsive to a variation in the capacitor discharge time which corresponds to a significant motion event.      In a preferred embodiment, when the pyrosensor is exposed to infrared motion, it generates a transient current, and the capacitor discharge time corresponds to the transient current. The signal processor circuit includes logic operable to compare the capacitor discharge time with a long-term average capacitor discharge time.  The signal processor circuit generates the electrical control signal only when the capacitor discharge time deviates from the long-term average capacitor discharge time by exceeding a predetermined threshold margin and/or satisfying other timing and/or pulse sequence patterns.  The logic of the signal processor circuit may be further operable to calculate  and update  the  long-term  average  capacitor discharge time based on the capacitor discharge time such that the logic filters out unwanted background signals and component tolerance variations, thereby creating a dynamic threshold system for detecting significant motion.

Abstract: An accessory device for a roller skate is disclosed, for use to block the wheels of this roller skate. This device comprises a plurality of elongated members that are made of non-slippery material  and sized to  snugly fit transversely between two of the wheels. These members are linked together, preferably by an elastic rope which is forming a closed loop. The device can be secured to the frame of the roller skate whenever required by placing each member between two of the wheels to prevent the same from rotating.  This device is very advantageous because it is inexpensive and very simple to install on a roller skate. It is also very light in weight and compact, thereby making it easy to carry.

Patent CA-2138184-C (CA)
IPC: G01S7/40
Filed: 1994-12-15
Granted: 1998-07-28
Abstract: Three independent signal sources (14, 15, 20) are used to statistically derive the power spectral density of the phase noise content of signals from each of them. This is accomplished by mixing (30) each of the signals two at a time (i.e., signal one with signal two, signal one with signal three, and signal two with signal three) and capturing the resultant difference signals, such as with a waveform recorder (11, 12, 13), for example. A servo electronics loop (25, 26) is used to remove the carrier and any long term signal drift from the resultant difference signals. Statistical analysis is then used to compute the composite power spectral densities of the the resultant difference signals, and to solve for the individual power spectral densities of the original signals. The present system (10) and method (40) uses the mathematical relationships between the three sources that have similar magnitudes of phase noise, to compute the power spectral density of the noise content of signals from each source (14, 15, 20). The present system (10) and method (40) requires a minimum of interconnect hardware and only three inexpensive waveform recorders (11, 12, 13), for example. Furthermore, the size, weight, and cost of producing the present phase noise test system (10) is relatively low.

Abstract: A system and method of supporting pause-resume in a video-on-demand service of a type which can accommodate multiple viewers sharing a common data stream is described. When a video server receives a performance request from one of the viewers for showing a particular video, it identifies and reserves a look-ahead stream. The look-ahead stream is another video stream which is scheduled to become available after a predetermined time period. When the video is commenced, a common data stream for the video is concurrently transmitted from the video server to reception equipment at the viewers' locations. Transmission of the common data stream causes the particular video to be performed on the viewers' reception equipment. When the video server receives a pause request and then a subsequent resume request from one of the viewers, it transmits the video via the look ahead stream instead of the common data stream.

Abstract: This disclosure is directed to a chuck system for a machine tool such as a lathe. It incorporates an elongate cylindrical body which terminates in a set of collet fingers having enlargements at the detail end whereby the enlargements define a circular body. The circular body is divided by slots to form collet fingers with enlargements at the ends of the collet fingers. A circumferential groove is formed having a registration shoulder for all of the lock jaw segments. Each lock jaw segment has a protruding tab. The tab is locked by positioning against the face of the groove and is registered against movement by jamming against a transverse post in the groove which shoulders against a conforming notch on the locking tab. A set screw holds the components in fixed location, and release is accomplished by unthreading the set screw.
